foreach over string enum

[Nrgyzer]

Hey guys,

I'm trying to iterate over an enumeration which contains strings like
the this:

enum FileName : string {
file1 = "file1.ext",
file2 = "file2.ext"
}

I already found this article: http://lists.puremagic.com/pipermail/
digitalmars-d/2007-July/021920.html but it's an enum which contains
integers instead of strings, thus I can't use min- or max-property.

Any suggestions -> thanks in advance!
